My eyes followed his pointing finger. The figure was moving. Gracefully it arose to its full height. The great cloud of corn-colored hair floated down about it, falling below the knees. Slowly, with a grace of movement comparable only with the slow soaring of a gull, she came toward me, walking on the bottom of the pool through the clear water as though she floated in air. * * * * * Fascinated, I watched her. Her eyes, startlingly large and dark in the strangely white face, were fixed on mine. There was nothing sinister in the gaze, yet I felt my body shaking as though in the grip of a terrible fear. I tried to look away, and found myself unable to move. I felt Mercer's tense, sudden grip upon my arm, but I did not, could not, look at him. "She--she's smiling!" I heard him exclaim. He laughed, an excited, high-pitched laugh that irritated me in some subtle way. She was smiling, and looking up into my eyes. She was very close now, within a few feet of us. She came still closer, until she was at my very feet as I stood on the raised ledge that ran around the edge of the pool, her head thrown back, staring straight up at me through the water. I could see her teeth, very white between her coral-pink lips, and her bosom rising and falling beneath the veil of pale gold hair. She was breathing _water_! Mercer literally jerked me away from the edge of the pool. "What do you think of her, Taylor?" he asked, his dark eyes dancing with excitement. "Tell me about it," I said, shaking my head dazedly. "She is not human?" "I don't know. I think so. As human as you or I. I'll tell you all I know, and then you can judge for yourself. I think we'll know in a few minutes, if my plans work out. But first slip on a bathing suit." I didn't argue the matter. I let Mercer lead me away without a word. And while I was changing, he told me all he knew of the strange creature in the pool. * * * * * "Late this afternoon I decided to go for a little walk along the beach," Mercer began. "I had been working like the devil since early in the morning, running some tests on what you call my thought-telegraph. I felt the need of some fresh sea air. "I walked along briskly for perhaps five minutes, keeping just out of reach of the rollers and the spray. The shore was littered with all sorts of flotsam and jetsam washed up by the big storm, and I was just thinking that I would have to have a man with a truck come and clean up the shore in front of the place, when, in a little sandy pool, I saw--_her_. * * * * * "She was laying face down in the water, motionless, her head towards the sea, one arm stretched out before her, and her long hair wrapped around her like a half-transparent cloak. "I ran up and lifted her from the water. Her body was cold, and deathly white, although her lips were faintly pink, and her heart was beating, faintly but steadily.
